Bárðarbunga in Iceland
Iceland has a large Earth event going on underneath her at the present moment. It is a Volcano underground that has not yet come to the surface. This magma is moving through solid rock under the ground and will cause a Jökulhlaup which is a glacial outburst flood. It is an icelandic terminology and this is triggered by geothermal heating and occasionally by a volcanic subglacial eruption, but it is now used to describe any large and abrupt release of water from a subglacial or proglacial lake/reservoir.
Seismic activity
There has been high seismic activity in Dyngjujökull in Norther Vatnajökull glacier since midnight. Over 700 earthquakes were detected from midnight to noon. Two earthquakes around and over 5 were detected in Bárðarbunga caldera. The first one, size 5,3 occurred at 00:09 HRS at the Northern edge of Bárðarbunga caldera. The latter occurred at 05:33 HRS, size ca. 5 at the Southern edge of the caldera. Both earthquakes happened at around 5 km depth.
